Laminated media are intended to conduct the magnetic flux in the plane (high resistance to limit the eddy currents). When fringing flux falls in perpendicularly to the plane, the surface for the eddy currents is no longer small. This will cause eddy current losses, which will reduce the efficiency of the application. A 2D FEM model for in plane losses in laminated ferromagnetic media due to fringing flux perpendicular to the plane is presented. This is done for one tooth of an axial flux permanent magnet motor with concentrated windings. Instead of using a homogenization method, all details of the laminated media are considered to become an accurate model.
